Our rotary Electric Encoders are tolerant to temperature extremes, EMI, RFI, magnetic fields, contamination, moisture, shock and vibrations. Their hollow, floating, rotor does not require bearings and is directly mountable on the host shaft.
The absence of ball bearings, glass disc, light sources and detectors, and low power consumption leave the Rotary Electric Encoder with virtually no failure mechanisms. It is, therefore, ideally suited to a wide range of applications, among them aerospace, military & defense, automotive, medical and robotic.
DS family of Rotary Encoders
The DS family of electric encoders provide exceptionally accurate, high resolution, absolute position. Their ring construction and very low profile allows compact, "friendly" mechanical integration. The DS family of encoders ranges from the DS-25 with 25mm OD and 7mm profile to the DS-247 with 247 mm diameter and 10mm profile. |

DS-37 Rotary, Sine/Cosine Absolute,
Electric Encoder™
The DS-37 is a member of the DS series, which is based on Netzer Precision Electric Encoder™ technology. This, state-of-the-art, technology offers many features, some unparalleled:
- Lowest profile (? 10 mm)
- High precision, absolute position output
- High tolerance to temperature, shock and moisture
- Tolerance to EMI, RFI, and to magnetic fields
- Very low weight
The holistic (1) structure of the Electric Encoder™ provides generous mounting tolerance, thus obviating the need for internal ball bearings. The absence of bearings, flexible couplers, glass disc, light sources and detectors, along with very low power consumption, make the DS-37encoder virtually failure free.
The internally shielded, DC operated DS-37 includes an electric field generator, a field receiver, a sinusoidally-shaped dielectric rotor, and processing electronics. The coarse/fine, analog output signals are proportional
to the sine and cosine of the rotation angle.
Demanding applications suited to the DS-37 include: Aerospace, medical, instrumentation, automation, etc. |

| Pulse encoders from Leine&Linde are a type of sensor used to feed back speed or position for rotational or linear movements. Encoders are often used on electrical motors in the paper and steel industries, cranes, robots and material handling systems as well as various types of measurement, testing and inspection systems. |

Model 800 Series (Heavy duty)
When the most robust, maintenance-free and cost-effective pulse encoder solution is sought after, the encoders in the Model 800 Series are the first choice of the majority of designers. The optional ADSTM (Advanced Diagnostic System) is a built-in system used for condition-based or preventative maintenance, guaranteeing the reliability of the application. Demanding environments and electrically or mechanically stressful installations are circumstances the encoders in the Model 800 Series are often exposed to and for which they are well-protected. Accessories and ready-made design solutions meant to guarantee operation and increase service life which reduce the total cost of the application are also offered as options for the encoder series.

Model 500 Series (Robust)
"Versatile" and "modular" are catchwords that differentiate the incremental and absolute encoders in the Model 500 Series of robust encoders. Used in many different types of industrial applications such as electric motors, cranes, elevators and general automation, the series' mechanical, optical and electrical interfaces have become industry standard. If the standard selection of interfaces does not suit the application's particular requirements, customised, cost-effective solutions may be provided with short lead times.

| Phoenix America Inc. rotary magnetic encoders employ magnetic based technology reaching multiple channel outputs with resolutions topping 10,000 counts per revolution. Phoenix America Inc.'s unique magnetic encoder design eliminates the challenge and expense of conventional encoder bearing systems aling with associated brackets, couplers and mounts. You won't find specifications on Bearing Materials and Bearing Life on Phoenix America Inc. magnetic encoders since they don't need to employ a separate bearing system. Your shaft and bearing system is all that is necessary. |

Incremental encoder is the term given to sensors for recording changes in position (linear or rotating) that can measure both the distance and direction of travel.
They are also known as optical encoders.
Unlike measuring systems that work continuously, incremental encoders have a solid measure with a repeating periodic counting track. The measurement is based on a directional reference and a count. |
